We shape ambitious spaces — from cultural landmarks to intimate interiors — with the rigor of complex public work and the agility of a focused studio.

We partner with clients who value design as a driver of identity, experience, and long-term value.

OstrowHarding is a full service architecture practice based in New York and Los Angeles. Our clients range from private developers and cultural institutions to hospitality brands and residential owners. We collaborate closely with the entire project team to discover unique opportunities within each site with an eye towards feasibility, invention and ambition. We guide the process to translate vision into built form, aligning design intent with real-world constraints.
